<p><P>PROBLEM TO BE SOLVED: To provide a high-frequency induction heating apparatus with which even in a slender-shaped work, the high-frequency induction heating can be applied without almost developing the bending, and the correction of bending is unnecessary and the heat-treatment, such as high quality hardening, can be applied. <P>SOLUTION: In the high-frequency induction heating apparatus for applying high-frequency induction heating to a slender-shaped work moving in the apparatus main body, a position regulating part composed of one pair of clamping members for clamping the work is arranged at the position near the high-frequency induction heating coil for induction-heating the slender-shaped work with high frequency, and this work is moved in a longitudinal direction in a state the position of the work is regulated by the position regulating part and also, the high-frequency induction heating to the work is applied in a state a prescribed gap is present between the work and the high-frequency induction heating coil. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
